CS8416K-CNZR

Audio Special Purpose Overview

The CS8416K-CNZR is a monolithic CMOS digital audio receiver manufactured by Cirrus Logic Inc. It receives and decodes digital audio data according to IEC60958, S/PDIF, EIAJ CP1201, or AES3 interface standards. The device features an 8:2 S/PDIF input multiplexer, low-jitter clock recovery, and flexible serial digital output ports. It operates with +3.3 V analog and digital supplies, while the logic interface supports +3.3 V or +5.0 V. The component is housed in a 28-QFN (5x5) package and supports sample frequencies from 32 kHz to 192 kHz.

Audio Special Purpose Procurement Notes

This part number is designated as 'Not Recommended for New Designs' (NRND). Verify current availability status and lead times, as this part may be subject to discontinuation notices.

Audio Special Purpose Selection Notes

Select based on required supply voltage compatibility; the VL pin accepts either 3.3 V or 5.0 V logic levels. Ensure the design accommodates the 28-VFQFN exposed pad package for proper thermal dissipation. Verify that the control interface requirements match either SPI or I²C modes supported by the device.
